Application filed October 15, 1910. Serial No. 587,267.

To all whom it may concern:

Be it known that I, JAM'ns PoI-NTON, a

subject of the King of England, residingat 147 Liverpool road, Birkdale, of Lancaster, England, have and useful Improvements in tors, of which the tion.

This invention relates to methods of and means for'charging air with medicaments, volatile substances, disinfectants, perfumes, and the like, and it has for one of its objects to provide an improved method of and means for effecting this purpose; and a fur ther object is to provide means whereby the quantities of air and medicaments, or the like, may be 'varied at will.

-By this invention, air can be charged with a vapor or volatile, medicament, and other substances, such as disinfectants, perfumes, and the like, and their relative proportions may be easily and quickly varied; while the apparatus will be found to be generally serviceable for this purpose, as Well'as for inhalation, and like purposes, where air charged with a vapor of ether, chloroform, or the like is required. And it will be understood that it is also serviceable for diffusing disinfectants, and the like in a room or chamber.

By the improved apparatus, air is caused to pass through a quantity of liquid medicaa closed vessel, bycausing by an e ector device, a partial vacuum the medicament. The air through the medicament and its vapor carin the county invented new Air-Impregnafollowing is a specificaiied by such air passes out into the atmosphere, mixed with the air by which the partial vacuum is caused above-the medicament. To vary the quantity of air mixed with the v medicament, air may be caused to mix with the vapor of the medicament and its carrier air before it becomes mixed with the air issuing from the ejector.

he apparatus comprises a closed receptacle or vessel having a tube open to the atmosphere, and extending from the upper part to'nearly the bottom of the vessel; and a second tube which passes upward from the upper end of the closed vessel or receptacle, its lower end being above the surface of the medicament or the like. To the upper end of this second tube is attached or fitted, an-

- like the air will become or the liketo be formed above which passes the sealb as to enable it to other tube containing an ejector which at one end, is fitted with causing air to be forced through nozz e; and at the other end mixing chamber, or other means. be a plain open end, for passing the medicamentized'air into the atmosphere. The second tube may be provided with means whereby air from the atmosphere can pass directly thereinto, without the medicament; and this means is provided with other means for regulating the quan tity of air admitted into this second tube; and such means for regulating this quantity of air may also serve to control the quantity of airpassing through the medicament. The first mentioned tube, which extends into the medicament, may be provided with a perforated or porous plate or sheet, or disk, at its lower end, or at a suitable part of its length, for causing the air descending this tube, to pass through the whole of the body of the medicament as it ascends through it before reaching the second tube. It will be nozzle means for understood that when the medicament or the like is in the character of a liquid, the air will bubble through the same before it reaches the second tube, while if the medicament is absorbed by porous material or the medicated or otherwise treated before it arrives at the outlet.

Apparatus constructed according to this invention, are shown in the accompanying drawings, in whicha Figure 1 is a vertical section of a simple form of apparatus. Fig. 2 is a sectional plan taken at the line 2-2 Fig. l. Fig. 3 is a similar view to Fig. I. Fig. 4 a sectional plan taken on the line 4-4 Fi 3 of a modification, and Figs. 5, 6, apd are similar vews to Fig. 1 exhibiting furthermodifications under this invention.

Referring to Figs. 1 and 2 of the drawings, a is the container or receptacle, and b .the seal or closure device for the same. 0

designates a tube which extends through the seal 6, and is open at its upper end, and terminates adjaeently to the bottom of the receptacle a. This tube may be so fitted in be adjustable, relatively to the bottom of'the receptacle,

with a nozzle,

passing through and thus enable air to be medicated. disinfected, or otherwise treated, to any desired degree. d designates the second or outlet tube which passes through the, said seal,

' which terminates close to the inner surface thereof. e designates the ejector tube containing a nozzle f, which terminates above the aperture leading from the second tube d into the tube 0. Air is supplied to the ejector nozzle by means of theejector tube e having at its end means for supplying air, such as a ball pump it of known form; but any other suitable known means maybe employed for this purpose. To the tube 6 at the op osite end to that of the ball pump, is provi ed an outlet nozzle i, which in the form shown in Fig. 1, is of spherical shape, and serves as a chamber for mixing the air from the ejector nozzle 7, and the medicated air passing from the receptacle or vessel a. The method of charging air by "this apparatus consists in forcing air I the ejector tube 6,

5 the medicament; and where the valve is conposition, coincide with through the nozzle f by means of the all pump it; and this operation causes? rtial vacuum to be formed above the ment contained in the receptacle (1; and this partial vacuum causes air to enter the inlet tube a and pass through the medicament bodily to the outlet tube (1, and thence to in which it comes into contact with the air issuing from the nozzle f; and the two quantities then pass into the mixing chamber '5, and owing to the shape of this chamber 71, these two quantities become intimately mixed with each other, and issue therefrom to the atmosphere equally medicated. Referring to Fig. 3, the parts a, b, c, and d, are similar to those shown in Figs. 1 and 2, while the ejector tube 6 is shown at an acute angle to the tube (1, and is provided at its discharge end with a nozzle 7'. In this modification is provided a second air inlet tube or by-pass k which is arranged within the receptacle, and has one end disposed below or in proximity to the outlet tube d; and this tube or by-pass it serves to admit passing through the medicament or the like. This second tube is is provided with means for regulating the inlet aperture thereof, the means shown comprising a pivoted valve plate Z, by the movement of which, the openmg of the inlet aperture can be varied. This valve may also serve for controlling the opening of the inlet of the tube 0, and thus control the supply of air passing through structed as shown in the drawings, this valve serves to control the inlet of both the tube a and tube k.

Referring Figs. 5, 6 and 7, that exhibited in consists in providing apertures m and a sleeve 01. provided with holes 0, which, when the sleeve is in one the apertures m; and

when in another position, no connection Fig. 5

medica" air direct to the tube d without the same to the modification. shown in the outlet tube at with exists between the two; and thus, when in this second position, the orifices m are closed. By this means the admission of air to the outlet tube d, and the quantity mixed with the medicated air can be varied as desired. In this Fig. -5 is illustrated a perforated plate ;0 attached to the lower end of the air inlet tube 0, and this air inlet late serves to equally distribute the air t rou'gh the medicament contained in the receptacle a. In Fig. 6 is shown a further modification of a means for controlling the admission of air from the atmosphere to the outlet tube at. This means is of similar construction'to that described with reference to Fig. 5, with the exception that the tube q is attached to the tube d, and is provided with a short ca 1 shown in dotted lines, the walls of suc cap being provided with holes whereby air is admitted into the tube 9, and the outlet tube 11. According to the number of holes in this cap r, so will be the fineness of regulation of air from the atmosphere to the tube d.

The modification shown in Fig. 7 comprises the forming of an enlarged portion on the tube at, suchas a valve chamber 8, and fitting a pivotally mounted valve t therein which serves to control an aperture in this valve casing s; and according to the amount of opening of this aperture so will be the amount of air admitted to the outlet tube (1.

By the above means it will be obvious that medicated, disinfected, perfumed, and other similarly treated air may be obtained to any strength desired, or any degree of strength required; and thus enable such an apparatus to be used for any purpose for which it may be found useful, such as for 1. An air impregnator comprising a closed receptacle, means for admitting air into the receptacle in the vicinity of the bottom thereof, an outlet tube connected with the receptacle, and out of contact with the contents of the receptacle, an containing a nozzle, and mounte upon and communicating with the outlet tube, and disposed transversely with relation to the same with the nozzle disposed over the outlet tube, and means connected with the ejector tube at the opposite end to that at which the impregnated air is delivered to the atmosphere, for forcing air through the nozzle across the top of the outlet tube in the ejector tube.

2. An air impregnator comprisingaclosed receptacle, means for leading air into the receptacle and discharging the same in the vicinity of the bottom thereof, an outlet tube connected with the receptacle, an ejector tube connected to the upper end of e'ector tube the outlet tube and disposed transversely name to this specification in the presence of with relation to the same, a nozzle located two subscribing wltnesses.
